Patented Feb. 18, 1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention has reference to new and useful improvements in Weather proofing and weather stripping also the rattle proofing of double hung windows.

The primary object of the invention is the provision of means for weather stripping and weather proofing double hung windows which consists of applying to the upper and lower sashes of a double hung window casement spring controlled weather strips adapted to bear against the outer surfaces of both the upper and lower sashes thereof to render said sashes weather proof, anti-rattling proof, and substantially burglar proof.

A further object of the invention is to provide means for guiding and weather proofing upper and lower sashes in such manner that the same are rendered anti-rattling and at the same time rendering the sashes easily movable in the casement as the spring controlled strips prevent binding therein due to warping of the sashes due to weather conditions.

A still further object of the invention is the provision of means comprising spring actuated weather strips adapted to bear at all times against both upper and lower sashes of a double hung window and in which the spring urging means is completely concealed from view.

An additional object of the invention is that the device may be readily and easily applied or installed to any double hung window of the usual type.

Additional to the foregoing objects is that of providing a device of the class indicated that is simple in construction and design and that is positive in its action and that may be cheaply manufactured and installed on any double hung window casement by a layman.

Other objects and advantages of the invention will become apparent with reference to the subjoined specification and the accompanying one sheet of drawings in which:-

Figure 1 represents a double hung window and casement looking from the inside of a structure and. showing my improved weather stripping as applied to the upper and lower sashes of a double hung window casement;

Figure 2 is an enlarged sectional detail view taken through both upper and lower sashes and showing my improved weather stripping applied thereto;

Figure 3 is a transverse section taken on the line '33 of Figure 2 and showing one side of the casement and illustrating the spring pressed strips for both upper and lower sashes of the easement;

Figure 4 is an enlarged fragmentary face view of one of the weather strips for the lower sash and illustrating the spring means for urging said strips against said window sash;

Figure.5 is an enlarged fragmentary face view of one of the strips for the upper sash of the window and showing the slightly modified spring means for urging this sash toward the dividing strip of casement; and

Figure 6 is a face view partially in section illustrating the slotted guide means for the outer strip of the easement.

Referring now more particularly to Figures 1 and 2 it will be observed that my improved weather stripping device consists of the usual casement 8 having lower and upper sliding and counterbalanced sashes 9 and Ill, respectively, of the usual type said sashes being slidable in the casement along the usual guiding strip II.

The lower or inner sash 9 is provided with spring pressed weather and anti-rattle proofing strips l2 and I3 and the upper or outer sash I0 is provided with similar strips I 4.

Referring now to Figures 2, 3 and 4 the inner strips I2 and I3 bear against the sash 9 and the strips I4 bear against the sash I0, one of the strips I2 being shown in detail in Figure 4 and showing slots I5 through which I6 extend and having at their upper and lower ends spring elements I! operating against fixed pins or screws I8 so that said strips are always normally urged against the inner face of the sash 9.

The strips I4 for the outer or upper sash I0 are arranged slightly different than the strips I2 and I3 in that the screws I9 are counter-sunk in apertures 20 slotted as indicated at 2|, Figures 3 and 6. In Figure 5 the spring elements 22 bearing against the pins or screws 23 illustrate the means for urging these strips against the inner face of the vertically grooved sash IEI, as clearly shown in Figure 3.

It is obvious that the heads of the screws I9 of the strips I4 must be countersunk or placed in the apertures 20 so that these heads will not contact the sliding sash I0 while in the sash 9 the strips I2 and I3 are arranged on the outside face thereof as shown.

It will thus be observed that I have produced weather stripping for double hung windows that places frictional tension against both lower and upper sashes 9 and II! respectively, and that said tension of the strips forces the same inwardly against the dividing strip I I and toward each other thereby preventing rattling of both sashes and at the same time preventing cold drafts from entering the inside of a structure so equipped and, furthermore, allows the sashes to be moved easily up or down in the easement.

I claim and desire to secure by Letters Patent of the United States the following:

In a device of the class described, weather stripping for windows, said weather stripping having transversely arranged guide slots formed therein, pins extending through said slots, additional slots formed in said strips, flat springs mounted in said strips and extending into said last mentioned slots, and fixed counter-sunk headed pins extending from the window casement and engaging said springs whereby said strips are urged tightly against the window sashes.

LOUIS STOLTENBERG.
